Build Your Own Java Performance Profiling Tool

An anonymous reader writes "IBM DeveloperWorks has an interesting look at creating a custom profiler using Java 5 and AOP. From the article: 'Profiling is a technique for measuring where software programs consume resources, including CPU time and memory. This article provides a list of best-of-breed features you might look for in an ideal profiler and explains why aspect-oriented techniques are well suited to achieving some of those features. It also introduces you to the JDK 5.0 agent interface and walks you through the steps of using it to build your own aspect-oriented profiler.'"

Re:Why?

[animaal]

I agree totally. Java is dead. We just have to get the message through to the huge numbers of organizations and developers who depend on the technology to get their jobs done. Oh, and then we have to come up with something better to replace it. Give me a little while... ;)

here's my profiler

[cygnus]

public class HomegrownProfiler {

public static void main(String[] args) {

while (true) {

System.out.println("Some people say this'll never be quite as fast as hand-tuned C.");

}

}

}

best-of-breed

Never use the word "best-of-breed" again. Or else.
